COIN SLIDE Joseph W. Srodulski, Chicago, Alll. Application September 29,1939, Serial No. 297,050 (Cl. 194-1) 3 Claims.

This invention relates to improvements in control mechanism for use invending machines and has as its principal object the provision of asimplified operating slide for effective movement to operate the vendingmachine by utilizing a tested coin te release a latch for the slide.

Another object of the invention is to simplify the construction of acoin slide by providing an improved guide means therefor which dispenseswith the expensive die cast sleeve structures heretofore employed insuch devices.

Another object is the provision of a full stroke mechanism arranged toguide the slide and to provide a reinforced ratchet for vcooperationwith a full stroke dog.

Another object is the provision of a slide having guidi-ng ribs along aportion of its length Working in slots in a stationary mounting membernear one end of the slide, a gliding shoe at the opposite end of theslide, and full stroke mechanism including a combined ratchet and guidebar coacting with a full stroke dog and providing a guiding rib on theopposite side of the slide from the first-mentioned ribs.

Yet another` object is the provision of a coin slide having a slot intowhich a tested coin ts to project through the slide normally to theplane thereof and a latch for the slide provided with a cam edge againstwhich the coin is'borne to cam the latch into released position.

Other objects, advantages and novel aspects of the invention reside inthe various details of construction as well as the arrangement and modeof operation of the parts of the preferred embodiment describedhereinafter in view of the annexed drawing, in which:

Fig. 1 is a vertical transverse section through the control unit;

Fig. 2 is a longitudinal Vertical section along line 2-2 of Fig. 1;

Fig. 3 is a horizontal section looking up from above the slide in thedirection of line 3-3 of Fig. 2; While Fig. 4 is a perspective of theslide, latch and dogging mechanism.

Referring to Fig. 2, the improved control mechanism includes anelongated control slide I having a handle portion at its front end I Iand provided on its under side with a plurality of guiding ribs I2 (Fig.1 also) spaced apart across the slide and extending in the lengththereof about two-thirds the distance to thecpposite or rear end of theslide proper.

At its inner end, the slide is provided with a shoe I3 (Fig. 4 also)secured to the under side thereof by screws I4 and having its under siderecessed as at I5 so as to provide runner surfaces I6 to facilitate thegliding movement of the slide at its rear end, the runner surfacesresting upon structure which is freed a horizontal supporting member IIconstituting a part of a housing structure including a front wallportion I8 in which there are spaced grooves to receive the several ribsI2 which effectively guide the slide at its front end.

Means for guiding the slide at its inner or rear end and also providingparts for cooperation with a full stroke dog mechanism, includes theprovision (Fig. 4) of an angle bracket having one side flange 2E!mounted by means of the screws I4 flush against the upper Side of theslide with a serrated edge portion 2l extending in parallelism with onelong edge of the slide. The other flange portion 22 of the angle bracketprojects upwardly and normally from the plane of the slide for slidingmovement in a groove' 23 (Fig. l) formed on the under side of a casting24 which provides a cover plate for the slide and also a vertical chutesection for guiding tested coins into operative engagement with theslide.

The cover casting is secured to the horizontal riding plate Il by meanssuch as the screws lo threading into suitable bosses in the casting.Thus, the movement of the vertical or projecting flange portion 22 ofthe dog ratchet 2t, in the groove 23, cooperates with the movement ofthe ribs I2 in the slots of the front wall of the housing to guide theslide accurately in its reciprocable movement. This is a simplifiedconstruction which greatly reduces the cost of manufacture of this classof slide because heretofore, eX- pensive die castings have been requiredin providing a sleeve in which the slide could move.

A full stroke dog 26 (Fig. 4) is pivoted on a pin 21. which extends intoa large boss 28 (Figs. 1 and 3) cast integrally with the cover member onthe inner side thereof and of a size adequate to provide an unusuallysturdy mounting for the dog, the boss 23 in fact being joined by a webportion 29 with the side wall of the casting and including a tappedportion to receive one of the mounting screws i9 for the cover plate.

The dog has a nose portion ita, which is normally positioned by actionof a spring 3D to engage or ride in teeth of the serrated ratchet edge2I to prevent inward movement (toward the right, Figs. 2 and 4) of theslide after the same has been pulled outwardly (toward the left) farenough so that the first ratchet tooth 2|a engages With the dog, itbeing necessary to pull the slide out the entire distance in order thatthe rear end 2lb of the ratchet be moved past the dog to permit thelatter to be swung in the opposite direction so as to idle ineffectivelyover the ratchet teeth when the slide is pushed inwardly again.

The guiding flange 22 on the ratchet is of adequate strength to preventthe inner end of the slide from swinging out of engagement with the dogWhen a blow is struck against the handle in an attempt to release thedog, and the mounting boss 28 is similarly constructed to provide a firmmounting for the dog.

Means actuated by a coin cooperably with the slide to release the slidefor full stroke movement, includes the provision of a cam latch 35 (Fig.4) pivotally mounted on the boss 36 on the under side of the covercasting, and having a cammed nose portion 31 arranged in advance of acoin slot 38 through the slide. The cam latch has a depending lug 39which projects into a longitudinally elongated slot 40 in the edge ofthe slide, the lug latching the slide against effective movement bypermitting a limited amount of idle or free-play longitudinaldisplacement of the slide in order to effect release of the latch means.Spring means 4| on the pivot boss of the cam latch urges the latter intoa normal position inwardly of the slide so as to position the lockinglug S in the slot in the edge of the slide. A depending boss 35d (Fig.l) is disposed just above the cam portion of the latch to prevent pryingthe latter away from the slide. A depending lug 42 on the cam latchengages the edge of the slide to limit the inward movement by thespring.

In the operation of the device, the coin is received from a suitabletesting apparatus (not shown) and guided by the chute section 25 intoposition to drop into the coin slot 3S when the slide is disposedinwardly, the coin dropping partly through the slot to rest on the floorportion Il in the region behind (to the right, Fig. 2) a dropout openingl la.

With the coin positioned as aforesaid in the slot 38, the handle Il isgrasped and pulled forward (left, Figs. 2 and 4) and because of thelength of the slot 49 the forward edge of the coin is brought to bearagainst the cam edge 3l of the latch lever, and as the slide continuesto move outwardly the latch lever 35 is cammed to withdraw the lug 39from the notch in the edge of the slide so that the latter is free tomove into fully retracted position, such movement carrying the coin inthe pocket 38 along the floor portion Il and into the drop-out openingila from which the coin moves into a suitable receptacle. Meanwhile, thedog 25, coacting with the ratchet means in the manner heretoforedescribed, makes it necessary to draw the slide out its entire lengthbefore the same can be restored. This is to prevent partial movements ofthe slide which would permit effective operation thereof a number ftimes using the same coin. The arrangement is such in the illustrativeembodiment that a stack of vendible articles (not shown), such as candybars, is disposed above the rear end of the slide and the shoe I3, sothat when the slide is retracted or pulled out, the bottommost articledrops onto the iioor l l in front of the end of the retracted shoe, andwhen the slide is pushed in, the rear end of the shoe bears against thecandy bar or other article and pushes the same into a discharge chute(not shown).

It will be apparent from the foregoing description that the rib means I2and the guiding flange 22 in the arrangement described are the principalmeans for guiding the slide in its operative movement; and it will alsobe apparent that the combination guide and ratchet means 21-22 isadvantageous not only because of its simplicity but also in View of thefact that any stress eX- erted upon the ratchet in a fraudulent attemptto force the slide, is taken up largely in the flange portion 22 and theguiding track 23 therefor and not in the slide itself, as is the casewith the old type of construction where the ratchet was formed in theedge of the slide. Moreover, the slide may be cast and any niunber ofribs I2 provided therein to make the same as strong as necessary. Thesimplicity and effectiveness of the latch means 35 is a furtheradvantage.

The various advantages and objects of the invention may be accomplishedby modifications of the particular embodiment specifically describedherein, and it is intended that the appended claims shall include allequivalent arrangements fairly coming Within their call.

Having thusv described my invention, what I claim as new and desire toprotect by Letters Patent is:

l. In a coin slide, a combination guide and full stroke ratchet in theform of an angle bracket attached with one flange flush against a sideof the slide and said ange having a serrated ratchet edge in thedirection of the length of the slide close to an edge thereof, saidangle bracket having its other flange projected normally from the planeof the slide, and engaged in guiding means extending longitudinally ofthe slide, said ratchet edge of the bracket being adapted forcooperation With a full stroke dog.

2. In a control mechanism for vending machines, an operating slide andfull stroke means therefor including an angle bracket mounted with thesurface of one flange thereof flush against a side of the slide, saidbracket having an adjoining flange projecting out of the plane of theslide at right angles thereto, stationary means providing a guide grooveinto which said projecting ange of the bracket fits, the flange portionof the bracket which is flush with the slide having an edge with ratchetteeth therein disposed closely parallel with a long edge of the slide,and a full stroke dog mounted at one side of the slide opposite saidratchet teeth and arranged for cooperation with the latter to permit theslide to move from an initial position in one direction and preventmovement of the slide in an opposite direction unless the slide has beenmoved a certain distance from initial position.

3. In a coin control, the combination with a reciprocable slide of dogcontrolled means comprising an angled member attached to one side of theslide with an edge portion disposed close to a long edge of the slideand provided with toothed formations for cooperation with av dog, saidangled member having a projection extending out of the plane of theslide to t into a guiding groove, stationary means providing a guidinggroove into which said projecting portion fits, and a dog cooperablewith said toothed formations to permit movement of the slide in onedirection from an initial position and prevent movement of the slide inan opposite direction until the same has been moved a predetermineddistance from initial position, any stress due to forcing the slidebefore the same hasbeen moved said predetermined distance being taken uplargely in said angled member and said groove means.
